In other words, is a RM series mixer ALSO REQUIRED to use the CS18ai simply as a control surface/recording interface for Studio One?!? I have read through both the user manual and quick guide and they only mention the input standard use/default settings as: "The CS18AI is primarily a control surface, but its rear panel includes a selection of audio inputs and outputs. These are convenient for providing talkback and for playing source audio from front-of- house." If the inputs can be used as direct source for tracking a few channels into Studio One, how are they configured? Unless I missed something, not covered in the manual. Thanks!
